One-minute video. It demonstrates how to make the test bars for measuring clay body drying and firing shrinkage, fired absorption, a bar for measuring water content and loss-on-ignition and a disk for measuring drying performance and soluble salts content.

Making test bars for the SHAB, LDW and DFAC tests
We will make bars of a clay body for the SHAB test (for shrinkage and absorption), a specimen for weighing wet, dry and then fired (to get water content and LOI) and a drying disk to measure drying performance and soluble salt content. |
Tests |
Drying Factor
The DFAC Drying Factor test visually displays a plastic clay's response to very uneven drying. It is beneficial to show the relative drying performance of different clays. |
